MARKING DEVICE.

Specification of Letters Patent.

Patented Feb. l8, 1921..

Application filed September 7, 1920. Serial No. 408,476.

To all whom t may concern.'

Be it known that I, MICHAEL BoNsiAnos, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improvement in Marking 13evices, of which the following is a specification.

rhis invention relates to a marking device.

It is the principal object of the present invention to provide a marking device Which is cheap and inexpensive in construction and may be readily adjusted to permit a Wide range of characters to be fixed on a desired surface. The invention contemplates the use of a form within which a plurality of type belts are mounted and posi- .tioiied around small selectively revoiuble gears, said gears being easily set to disclose the desired character in a position for marking.

The invention is illustrated by Way of example in the accompanying drawings, in which:

iiigure 1 is an enlarged vienr in section through the marking device, as seen on line 1-1 of Fig. 2. y

Fg. 2 is a view in perspective of the device.

Fig. 8 is a fragmentary view drawn on a reduced scale and showing one of the operating gears and the manner in which it engages the type band.

Referring more particularly to the drawings: 10 and 11 indicate side frame members of the stamping device, Which members are held together by a U-shaped metal plate. 12, this plate extending along the opposite sides of the members and across one end thereof, thus allowing the opposite end to be opened as indicated at 13 in Fig. 2.

The side members 1() and 11 may be satisfactorily formed of Wood and will thus provide bearings for a plurality of shafts 14 and 15. The shaft 111 is secured across the compartment formed Within the structure and near the opened end thereof. This shaft is preferably provided with bearings 1G, upon which are mounted a plurality of freely revoluble gear disks 17. The shafts 15 which extend through the side -Walls 10 and 11 are arranged in parallel spaced relation to each other and the shaft 111. These last named shafts may be of any desired number and are disks 18 .and 19.

The disks 19 are preferably keyed to the shafts While the disks 18 are mounted for rotation thereon and are formed With eX- provided to rotate gear tension hubs 20 which project through the tions adapted to register with projectingr teeth 22 on the gear disks 17, 18 and 19. The outer faces of these bands carry type 28. In some instances these type represent the letters of the alphabet and in others numerals. This may be determined as de'- sired, although for the purpose of the presentdescription it is preferable to have the outermost type bands carrying letters ofthe alphabet and the intermediate bands carrying numerals. In this connection it Will be also noted that the bands are of different lengths, graduating toward the center.

Movement of the bands to bring a desired one of the type in register with the opening 13 is brought about by the index members 24, which are secured in one instance to the ends of the shafts 15 and in the other to the extension hubs 2O of the gears 18. The characters represented by the type are indicated on the faces of the members 10 and 11, so that thev fingers of the members 24 may be readily adjusted to register with any one of the characters selected, this movement having a direct bearing upon the movement of the type bands and insuring that a corresponding character will be brought to register with the opening 13 in the end of the frame.

1n operation of the present invention, the structure is assembled as shovvn in the drawings, and by rotating the various index members 2d the disks 18 and 19 will be adjusted and will positively move the type bands 21 to cause a series of type characters Y Ito register in the opening 13. The characters may then be inked or otherwise prepared for marking and may then be impressed upon a plain surface. i It Will thus Vbeseen thatthe invention here invention as claimed. i

1 "Having thus described my inventionvhat I claim and desire to secure by Letters Patentis:j

` l. The Vcoi'nbinationY in a marking device of a frame Work open at one end "and closedV at the opposite end, a'series of transverse shafts `having hubs` journaled successively fromfthe -closed'toward the open end, and with gear disk mounted upon the shafts, a single shaft fixed in the frame contiguous Vto the' open end, gear disks jrournaled 'onsai'd shaft in `planes corresponding with the first Vnamed disks, endless type bands extending around the cooperating upper and lower dlsks, said bands being Vof decreasing lengths from the outermost disks tothe innermost disks, and means for independently turning the upper shaft'hubs,` and advancing the Y type belts.

, 2. The combination in a marking device of a frame Work open at one end with trans- Y verse shafts Vhaving hubs journaled suecessively therein between the open and the closed end of the frame, toothed disks fixed upon the shafts, a shaft fixed Within the frame contiguous to its open end, with toothed disks turnable freely on the shaft, and in planes With the rst named disks, endless type belts movable around the alined pairs of disks7 index fingers fixed to the outer ends of the turnable shaft hubs, and corresponding characters on the exterior of the frame, and which the fingers are movable to indicate corresponding type von the belts. '3. In a device of the character described,

a frame structure having a printing open ing at oneV end7 a fixed shafty carried the frame adjacent said opening, a` plurality of disks freely revoluble upon said shaft, a pluralityof revoluble shafts carried by the frame in spaced paralleled relation to each other and the fixed shaft, a disk keyed on each of said shafts and disposed in the same plane With a disk on tliefixed shaft, means Y or selectively rotating saidi shifts, vendie'ss type carrying belts disposed'around the pairs of alined disks andV other disks carried by the revoluble ,shafts and'disposed in Vplanes With disks onV the fixedshaft, andnieans Vfor rotating said last named disks indepen dently of the shafts.

In testimony `whereof I have hereuntosct my hand in the presence of two subscribing Witnesses.
